Lakeshore areas of conservation interest: Characteristics of nursery areas of the threatened lake‐dwelling grayling, Thymallus thymallus

Aquaculture, Fish and Fisheries
Research‐based knowledge is essential for effective conservation and restoration of threatened aquatic species and habitats. Here, our aim was to gather this knowledge on the lake‐dwelling grayling (Thymallus thymallus), typically a riverine fish.

Demonstration of an instream flow model to accommodate a threatened tiger beetle in riverine dune habitat

Insect Conservation and Diversity, EarlyView.
Burrows of the threatened Gibson's Big Sand Tiger Beetle in riverine dune habitats are susceptible to flooding through managed flows. HEC‐RAS modelling identified the flow thresholds above which flooding would occur for burrows and affect the beetle larvae. These findings provide instream flow guidelines for conserving this threatened species and guide

Reproductive parameters of wild and hatchery‐reared sea trout (Salmo trutta m. trutta L.) females from the Łeba River (southern Baltic Sea)

Journal of Fish Biology, EarlyView.
Abstract Sea trout Salmo trutta m. trutta L. has high socioeconomic and ecological importance in the Atlantic region; therefore, stocking hatchery‐reared fish is widely practiced for stock enhancement and recovery of wild populations. In this study, fecundity of wild and stocked hatchery‐reared sea trout sampled from the Łeba River (southern Baltic Sea

Lacustrine algal limestone reservoir in western Qaidam Basin, China

, 2015
Compared to marine carbonate around the world, lacustrine carbonate is relatively scarce. Much less attention has been paid to it. Lacustrine carbonate, a product of mixed deposition of continental clastics and carbonate under special conditions, can be ...

Speciation of European bullheads (Cottus spp.): The next problem for taxonomy of northern freshwater fishes

Journal of Fish Biology, EarlyView.
Abstract High morphological and ecological diversity displayed by European bullheads led Freyhof et al. (2005) to describe 15 nominal species. However, the basis for declaring these nominal species is contentious due to a lack of rigorous statistical analysis of morphological variations among populations, limitations in the inferences made from ...

Genetic composition of facultatively anadromous brown trout Salmo trutta L. in a freshwater‐lake system

Journal of Fish Biology, EarlyView.
Abstract Brown trout (Salmo trutta) has adapted to a wide range of habitats and displays a variety of life‐history strategies. Being facultatively anadromous, populations without migration barriers to the sea consist of both resident and anadromous individuals in different proportions.
